Abu Muḥammad al-Ḥasan ibn ‘Alī ibn al-Ḥasan ibn ‘Alī ibn ‘Umar al-Ashraf ibn ‘Alī Zayn al-‘Ābidīn (Medina, ca. 844 – Amul, January/February 917), better known as al-Ḥasan al-Uṭrūsh ("the Deaf"), was an Alid Shia missionary of the Zaydi sect who re-established Zaydid rule over the province Tabaristan in northern Iran in 914, after fourteen years of Samanid rule.
In the 2000s the government has been fighting numerous rebel groups, such as the one led by Hussein al-Houthi's Zaydi movement Shabab al-Mu'mineen, "The Young Believers".
Actually, the Zaydi Revolt continued until 785 and re-erupted in Tabaristan under the leadership of the Zayd ibn Ali's son, "Hasan ibn Zayd’ūl-Alavī." His revolt attracted many supporters, among them the ruler of Rustamids, the son of "Farīdūn" (a descendant of Rostam Farrokhzād) "Abd al-Rahmān ibn Rustam" who was well known by the name of "Bānū-Bādūsyān," worth mentioning.
